Maybe I misunderstood the problem, but it seems to me that the names
of the built-in classes should always be returned by a call to help.
So instead of searching for __DEFINE in the output of routine_info(),
Resolve_Obj could instead build a list of class names from the output
of help:

help,/objects,/full,output=hobjs
;pick only the output lines with class names:
hobjs=hobjs[where(strpos(hobjs,'** Object class') ne -1,nclasses)]
classes=strarr(nclasses) ;array for the known class names
;extract the class name from the rest of the help information:
for i=0,nclasses-1 do classes[i]=(strsplit(hobjs[i],' ,',/extract))[3]

Which when I run in a clean session in IDL 7.1 gives me 63 class
names.
